OBJECTIVETo evaluate the feasibility of facial profile reconstruction by use of structured light three-dimensional scanning technique.

METHODSBased on Gray-code and phase-shifting method, the self-developed three-dimensional optical measurement system was used to acquire the primitive point data of a volunteer's face and cast of the face. All the datum records were processed and analysed with Imageware and Geomagic software to reconstruct a three-dimensional face model.

RESULTSCompared with the conventional impression method, the structured light three-dimensional scanning technique reconstructed facial profile with smaller deformation.

CONCLUSIONSBased on Gray-code and phase-shifting method, the self-developed optical measurement system captured three-dimensional facial profile accurately. It would be helpful to the three-dimensional reconstruction of the facial profile defect.
